Title: Improvements in the production of methanol
IPC: C07C29/149
Filed: 1949-09-30
Abstract: Methanol is produced from a mixture of carbon monoxide and hydrogen by formation and hydrogenation of methyl formate in two different reaction zones in a cyclic process, the gas mixture circulating permanently with replenishment, and both reactions being effected at below 100 atmos. and below 200 DEG  C.  Synthesis gas containing H2 and CO in 2 : 1 ratio may be reacted with an alcoholic suspension of an alkali alcoholate at 80-120 DEG  C. and 30-60 atmos. to form methyl formate.  The gases containing methyl formate are contacted with hydrogenation catalysts, especially catalysts containing at least 1 atom of Cr to 10 of Cu, such as copper chromite, to which alkaline earth and heavy metal oxides, and carriers of large surface area may be added, at 130-170 DEG  C. Methanol is removed by cooling and the gases recycled to the first stage after make-up gas is added. Methyl formate present in the methanol may be separated by distillation and returned to the second stage.  The Specification as open to inspection under Sect. 91 comprises also a single-stage process wherein the alcoholic alkali alcoholate contains the hydrogenation catalyst in suspension. This may be effected at 100-150 DEG  C. and 30-60 atmos.  A second hydrogenation to convert residual methyl formate to methanol may be carried out.  A shaking autoclave or tower reactor may be used. This subject-matter does not appear in the Specification as accepted.

Abstract: 819,373. Coin-freed apparatus. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Nov. 22, 1957 [Aug. 22, 1956], No. 25661/56. Class 27 A prepayment mechanism controlling, for example, a television receiver, on a time basis, or for charging for quantities of a commodity such as gas, water or electricity comprises a displaceable coin receiver 1 in which coins of differing denominations are held in such a position that they displace a spring-loaded control lever 6 by amounts according to their diameters, the return of the lever under the action of its spring setting forward a comparison or differential mechanism 17 by the requisite amount. The coin, after insertion through a slot having a gauge plate that tests it for excess thickness and diameter, rests on the hub of a shaft 3 carrying a disc 1 on which are three driving rollers 2. On rotation of the shaft by a knob 23, one of the rollers drives the coin against a pair of pins 28, 29 on the lever 6 and tilts it about a pivot 7. When the lever has moved the full amount according to the particular coin, one of three raised portions 30 on the disc 1 engages a pin 31 on a lever 10 and pins 32 and 33 on this lever are depressed to push a pawl 8 into one of the notches in a disc 13 geared to the trip cam differential 17. For a sixpence, the pawl moves by one notch spacing and for a shilling by two spacings and when the coin passes the pins 28 and 29 and is ejected, the return of the lever will set on the differential by one or two spacings. The pawl fits closely in the notches so that, if a coin anywhere between the two or more predetermined sizes is inserted, the pawl overlaps a notch and cannot be pressed into it. The pawl 8 is frictionally pivoted at 9 and, on return of the lever 6, is disengaged from the notch by the engagement of a pin 37 with a fixed abutment. In order to prevent overshooting of the disc 13, an extension 6a of the lever 6 passes a location roller 18 into one of the notches and, to prevent reverse rotation, a pawl 34 is provided. Casings. The shaft 3 has a bush 21 locating in a hole in the case 22 and a cover plate 24 over the back of the case is secured by two slotless screws having nuts fitted inside the case and accessible only on removal of a coin box at the bottom of the case.

Filed: 1938-09-02
Abstract: 518,692. Capsuling. HARRISON, A. G. Sept. 2, 1938, No. 25784. [Class 125 (ii)] Caps are secured to bottles having a crimping groove in the neck thereof by means of a resilient expansible annulus, the internal diameter of which in unstressed condition is less than the least diameter of the groove, the annulus being pushed laterally over a positioned cap until it is in alignment with the crimping groove, and is thereafter raised whilst the cap is held against the mouth of the bottle. The expansible annulus may be a spiral spring, or of rubber of circular, semi-circular or other cross-section. A suitable hand tool comprises a handle 1 and bell mouth 3; the expansible annulus 6 is located ina groove 8 and embraces a piston 4 slidably mounted against the action of a spring 9. The tool is applied to a bottle and cap 11 as in Fig. 1 ; pressure on the handle 1 against the spring 9 causes the annulus 6 to be lowered until it is opposite the crimping groove 7, Fig. 4, where it contracts and effects crimping; release of the pressure allows the spring 9 to expand, whereby the annulus 6 is raised whilst the cap is held down by the piston 4. The groove 8 for receiving the annulus 6 may be of other cross-sections, e.g. rectangular, to receive an annulus of semicircular cross-section, elliptical or of conical form for an annulus of circular cross-section, the latter shape assists the contraction of the annulus into the crimping groove. The handle 1 may contain a screw 14 which is used for withdrawing the piston 4 for cleaning purposes, and by screwing into one of the air holes 17 for assisting in the removal of the annulus 6 for cleaning purposes.

Abstract: 279,062. Compagnie pour la Fabrication des Compteurs et MatÚriel d'Usines a Gaz, and Soc. dite L'Action Ó Distance. Oct. 13, 1926, [Convention date]. Reciprocating and oscillating machines. - An arrangement of gearing mainly applicable for resetting clock hands from a distance is electrically driven whilst in the embodiment shown in Fig. 3, the main clock drive is also effected by electrically operated means. The supplementary drive for resetting the hands is obtained by passing an alternating-current through windings 8, 9 in series with a condenser 10 serving to energize pole-pieces of a magnet with a resonance frequency to which the natural periodicity of a vibratory magnetic strip corresponds. The vibrating strip drives through ratchet gearing 14 the element 16 of the toothed gearing. The clock hands are normally driven through toothed and ratchet gearing 64, 60, 69 operated by electromagnetic circuits 51, 61, 52, 62 resonant to alternating-currents of different frequencies, the co-operating magnetic strips 53, 54 having corresponding periods of free vibration. When the circuit 51, 61 is energized, the toothed element 65 is rotated, operating an arm 71 which can oscillate between stops 73, 74. When the arm 71 reaches the limit of its stroke the gear train continues to be operated idly. The return stroke of the arm 71 is effected by energizing the circuit 52, 62. By passing alternately at suitable intervals currents of the requisite frequencies through the main circuit 1, 2, the minute hand of the clock is advanced at the required rate.

Abstract: 1,113,683. Gramophones. NAHMA A.G. 18 June, 1965 [19 June, 1964; 12 Aug., 1964], No. 25864/65. Heading G5R. An arrangement repeatedly playing any selected portion of a gramophone record for teaching or advertising purposes permits the starting position to be adjusted without mechanical reaction on the pick-up. An inclinable lever cooperates with the pick-up for returning it slidably along the lever to the starting position. In the arrangement of Fig. 5, T is the tone arm of a conventional gramophone to which the arrangement of the invention has been attached. A mechanical or magnetic sensor 58 whose position is adjusted by a mechanical linkage (Fig. 7, not shown) from the knob 76, determines the end of desired portion of the record and initiates the repeating process by starting a motor (89, Fig. 6, not shown) supplied by a battery alongside. The motor raises an arm 97, so that the tone arm is lifted off the record and then slides down the arm until it strikes the stop 78 whose position is adjusted by the knob 80. The arm 97 falls (because the tone arm has left the sensor 58) and the tone arm slides down the conical side of the stop 78 to recommence playing the record. Switch 100 initiates the repeating process at any time. In another embodiment (Fig. 3) the pick-up 22 can slide freely on an arm 24 which is lifted on a pivot 26 when the pick-up is to return to its starting position. The record is driven conventionally by a motor whose speed is controlled by a governor and brake.
